The Icebreaker Merino Everyday Half Zip long-sleeve shirt for women offers comfort in any weather and is just as suitable for alpine sports as it is for everyday wear. This close-fitting top with a half-length zipper is made from rib-knit merino wool that cools in warm weather and insulates in cold weather – ideal worn on its own, under a midlayer, or under a jacket. The set-in sleeves make it comfortable to wear under a backpack, and the zipper provides quick ventilation when needed.
